NOTE:  

The expected coverage from the GTX 328 is limited to “line of 

sight”.  Low altitude or aircraft antenna shielding by the aircraft itself may 
result in reduced range.  Range can be improved by climbing to a higher 
altitude.  It may be possible to minimize antenna shielding by locating 
the antenna where dead spots are only noticed during abnormal flight 
attitudes.
